Bearings • Thrust Bearings
Thrust bearings are rotary bearings that allow rotation between parts and support a high axial load at moderate speeds. Design varieties include ball thrust bearings, tapered roller bearings, fluid bearings and magnetic bearings. Due to their inability to support radial loads, thrust bearings must be paired with radial bearings for radial load support. They are offered as flat race thrust bearings, one directional, grooved race thrust bearings and two directional, grooved race thrust bearings.

NSK Ltd. offers thrust cylindrical and spherical roller bearings. Thrust cylindrical roller bearings are thrust bearings with cylindrical rollers and machined brass cages. They have high axial rigidity that can only support heavy axial loads. Thrust spherical roller bearings are thrust bearings with convex rollers and machined brass cages for horizontal shaft or high speed application. If requested, the E type offers a pressed cage for high load capacity. They are self aligning and resistant to mounting error or shaft deflection.
NSK offer ball thrust bearings and spherical thrust bearings. Double direction thrust ball bearings support thrust loads in both directions at high speeds. They are made of washer like bearing rigs with raceway grooves for the balls. NSK Spherical Thrust bearings support extremely heavy thrust loads in a single direction at low to moderate speeds; it can support some radial load while thrust load is imposed. The spherical shape of the outer ring raceway was designed especially to handle misalignment.
